I did not write correctly.
When I select source drive on the next step it list all my partitions and ask me to select the one that I want to image.

The problem is that it does not let me to save that partition image to different partition on the same drive.

I never used this (wilbertni is the chap who know it well), but I would think it should be able to image one partition onto another partition as long as the target partition is FAT-formatted and has enough free space. However, potential problem areas could very well be your SATA-interface and/or Vista!

That said, even if you figure out how to do it, it's really a bad idea! Your target should be another physical drive, and preferably an external drive!
